PVC鹽霧箱與玻璃鋼鹽霧箱材質的質量對比
鹽霧試驗箱為人工氣候環境，三防（濕熱、鹽霧、霉菌）試驗設備之一，是研究機械、國防工業、輕工電子、儀表等行業各種環境適應性和可靠性的一種重要試驗設備。
Salt fog test box for the artificial climate environment, three (damp heat, salt spray, mold) one of the test equipment, is an important test equipment of machinery, light industry, defense industry, electronic instrument industry and various environmental adaptability and reliability.
一、鹽霧試驗箱使用材料對比
A, salt fog test box using the material comparison
（1）、玻璃鋼殼體采用不飽和樹脂、固化劑、滑石粉、顏料等混合，經壓模成型、拼裝組合而成，隨著時間的流失表面會泛黃不宜擦洗。而塑料殼體則選用進口硬聚氯乙烯、聚丙烯、合成碳酸等塑料板材經高溫模壓成型，再經刨、銑、磨等工序，后高溫焊接而成。
(1), glass steel shell made of unsaturated resin, curing agent, talcum powder, paint mixing, after compression moulding, assembled with the loss of time, the surface of the yellow should scrub. While the plastic shell body is imported hard polyvinyl chloride, polypropylene carbonate synthesis, plastic sheets by compression molding at high temperature, and then the planing, milling, grinding and other processes, the high temperature welding.
（2）、玻璃鋼殼體若長時間做高溫試驗極易使箱體老化，一旦漏水則基本無法維修，從而降低使用壽命。塑料殼體選用進口耐熱材料，試驗溫度可達80℃，塑料接縫采用高溫焊接，滲漏。
(2), glass steel shell if long time high temperature test can easily make the body aging, once Water Leakage is unable to repair, so as to reduce the service life. Plastic shell using the latest imported heat-resistant material, test temperature up to 80 ℃, plastic joints using high temperature welding, never leakage.
（3）、玻璃鋼鹽霧試驗箱箱蓋仍采用樹脂材料內置鐵板背后用鐵制鉸鏈開啟極不方便。并且該設備為腐蝕實驗設備，鹽霧極易造成對金屬的腐蝕作用，因此鐵制鉸鏈是不可取的。新型鹽霧試驗箱箱蓋則選用進口増強型透明聚氯乙烯板材背部采用自制塑料鉸鏈、重量更輕、開啟更方便。整個箱蓋全透明試驗時里面試品及試驗狀況可一覽無余。
(3), glass steel, salt fog test box cover still use built-in behind resin material iron with iron hinge open very inconvenient. And the equipment for corrosion test equipment, salt spray, extremely easy to cause the corrosion of metals, so the iron hinge is not desirable. The new salt fog test box cover is made of imported enhancement type transparent PVC sheet back with homemade plastic hinge, light weight, convenient opening. The box cover full transparent test sample and test condition inside can take in everything in a glance.
二、鹽霧試驗箱設計配置對比
Two, salt fog test box design configuration comparison
（1）、玻璃鋼采用底部加熱絲隔套干加熱方式給箱體供溫，此種方式較原始，容易使箱體老化而降低使用壽命。塑料箱體采用底部水槽加熱，選用鈦合金材料遠紅外加熱方式。這種方式升溫快，溫度比較均勻散布于箱體每一個角落，所以更容易控制。
(1), glass steel using bottom heating wire sleeve of dry heating mode box for temperature, this way than the original, easy to aging and reduce the service life of the box. Plastic box with a water tank at the bottom of the titanium alloy material heating, far infrared heating method. This way, fast heating, temperature is more evenly spread in the body every corner, so it is easier to control.
（2）、PVC鹽霧試驗箱增加了鹽水預熱裝置，可使鹽水溫度與箱體溫度保持一致，使試驗時箱內溫度波動更小，可控制在0.1℃之內。且鹽水箱采用內置式，不占空間，結構更為合理。玻璃鋼鹽水箱需另外配制，掛于箱體后背處，且鹽水溫度隨著環境溫度變化而變化，致使試驗時箱內溫度波動較大。
(2), PVC salt fog test box increased brine preheating device, can make the water temperature and body temperature stays the same, to test the temperature fluctuation is smaller, can be controlled at 0.1 ℃. And the salt water tank with built-in, does not occupy a space, the structure is more reasonable. Glass steel salt water tank additional preparation, hang on the box at the back, and brine temperature with the environmental temperature changes, resulting in test the temperature fluctuation.
（3）、PVC鹽霧試驗箱采用兩級缺水保護及超溫保護裝置，一有缺水及溫度異常會自動關機后報警，玻璃鋼鹽霧箱目前僅有箱體超溫保護。
(3), PVC salt spray test box adopts and overtemperature protection level two water protection device, a shortage of water and temperature anomalies will automatically shut down after the alarm, glass steel salt spray box at present only the over temperature protection.
（4）、塑料鹽霧試驗箱新增加了鹽水過濾裝置而玻璃鋼鹽霧試驗箱則沒有鹽水過濾裝置，試驗時噴嘴不會堵塞確保在試驗時間內正常噴霧至試驗結束。
(4), plastic salt fog test box adds a new filtration device and the glass steel salt fog test box is not salt water filtering device, test to ensure that the end of spray nozzle is not blocked the normal to the test in the test of time.
（5）、鹽霧試驗箱的飽和器裝置的設計更加科學，采用目前*的鈦金屬加熱器及出氣濾水裝置和飽和器低水位報警保護，可連續噴霧達72小時而不用加水。
(5), device design saturated salt fog test box more scientific, titanium metal heater current domestic advanced and outlet water filtration device and saturation of the low water level alarm protection, can continuously spray up to 72 hours without water.
（6）、鹽霧試驗箱的密封槽的設計更具人性化從而在試驗結束后很輕易地將水放干，而玻璃鋼則沒有放水設計，須用物件把水吸收。
(6), salt fog test box sealing groove design of more humane and at the end of the experiment easily drained, and the glass steel is no drainage design, must use the water absorption object.
三、節能降耗對比塑料鹽霧試驗箱更采用了節能降耗之功能，大大減少了電能資源更給使用廠商節約了成本。
Three, energy saving compared with plastic salt fog test box with the energy saving function, greatly reducing the energy resources to use vendor cost savings.
